Detailed description the drawing

1a shows an overview of an inventive arrangement on a printing press 1 and thus a system with a cold generator, which is preferably designed as a refrigerator, and a cooling device 3 , which is designed here as a free cooler. As in 1d is better seen, is the cooling device 3 preferably a Adiabatfreikühler, ie a spray device 31 allows the improvement of the cooling capacity due to evaporative cooling. The spray device can preferably via a water pipe z. B. be supplied with water, and is preferably only turned on when an improvement in the cooling capacity is needed.

In 1a the illustrated printing machine has three different areas 11 . 12 . 13 with three different temperature levels, which via an NT tempering 51 , an MT tempering point 52 and an HT tempering point 53 are tempered. The NT tempering point 51 and the MT temperature control point 52 are in 1c shown enlarged example.

In such an arrangement, as in 1c only by way of example with regard to the tempering points 51 . 52 is shown, in principle, each of the temperature control 51 . 52 . 53 a separate primary circuit 81 which is designed so that the heat flow through a heat exchanger 681 . 682 to a secondary circuit 82 is deductible.

One separate primary circuit in the sense described can as be formed open primary circuit, in which the fluid is partially consumed at the tempering point, such. B. with fountain solution, or as a closed primary circuit, where at every point the primary circuit of the inflow is equal to the outflow.

Furthermore, it is fundamentally conceivable for each or some of the temperature control points to have a circuit through which a process fluid flows, such that the heat flow is transmitted together with the circulating process agent, so that the heat flow is coupled to the flowing carrier mass of the process fluid flow. This is in 1c is exemplified by the lines which up to the respective tempering 51 . 52 rich and between the primary circuits 81 are shown. As in 1a It can be seen that these lines are components of sub-branches 65 a central heat exchange system 6 that directly with the heat exchange rice 62 communicate so that via a central inlet 631 the heat exchange circuit 62 Heat exchange fluid in the partial feed 651 of the sub-branch 65 can flow, can reach the temperature control point and from there via a partial flow 652 of the sub-branch 65 back to a central flow of the heat exchange circuit 62 can get. This design can be formed at the tempering "open" and / or closed.

As Therefore, both designs of temperature control can be represented be advantageously combined. But this is not absolutely necessary so that one of the designs can be sufficient.

The temperature-controlled heat exchange fluid can via the heat exchange circuit 62 be passed to other tempering, which z. B. in the warm-up phase of a printing press may be useful to the still cold other tempering the waste heat of another tempering for Ver to make available. This can be done directly via cross connections 653 . 654 take place between the sub-branches of the temperature control, as in 1a and 1b is represented by the horizontally illustrated lines, which is exemplified an exchange of heat exchange fluid between the sub-branch of the NT temperature control point and the sub-branch of the MT temperature control point. Thereby the cross connection leads 653 from the NT temperature control point to the MT temperature control point and the cross connection 654 back.

To divert the fluid flow accordingly are valves 661 . 664 intended. With appropriate design of the valve 661 and depending on the valve position, however, a fluid flow could also be from the central inlet 63 coming over a section of the cross connection 653 to the heat exchanger 681 the NT tempering point flow to cool the NT tempering. This can especially at low outdoor temperatures, eg. B. be useful in winter, when the heat exchange circuit 62 is used for cooling and as shown with a cooling device 3 is in heat exchanging connection. Depending on your needs, the heat exchange circuit 62 over the bypass line 67 and the bypass valve 671 for this purpose with the cooling device 3 be connected or shut off from this.

Depending on the minimum outdoor temperature at the operating times, it may be preferred if the chiller 2 the NT temperature control station permanently cools, ie whenever a waste heat has to be dissipated.

Since an NT tempering can usually be cooled to about 10 ° C, the chiller becomes 2 preferably designed to be so powerful that in addition at least a portion of the heat load of MT cooling points can be dissipated, z. B. if the free cooler is no longer sufficient with increasing ambient temperature.

The DC link supplies via the cross connections 653 . 654 the MT temperature control point with the cooling side of the cold generator 2 , The waste heat of the cold generator 2 Again, it is preferred to the heat exchange fluid in the heat exchange circuit 62 dischargeable.

A corresponding circulation in the circuits, depending on Valve positions will change their course preferably generated via circulation pumps, as needed can be switched on.

Preferably, at the individual temperature control points, 3-2 way valves and associated bypasses can ensure a constant temperature at the temperature control points, as with respect to the MT temperature control point 52 above the heat exchanger 682 is shown by way of example.

The HT tempering point (s), which are to be cooled to a temperature of generally above 50 ° C., are preferably used all year round via a cooling device configured as a free cooler 3 cooled. In this case, it is also advantageous if the other temperature control points which regularly have operating temperatures which can not be cooled or cooled uneconomically via a free cooler all year round, in the heat exchange circuit 62 shut off such that too hot a heat exchange fluid does not reach them.

at Such a tempering system is therefore particularly advantageous that all three tempering with each other either of the cooling capacity and / or participate in the waste heat and / or via a Ambient temperature without or with only a small amount of external energy tempered are.

So can z. B. a printing operation will be recorded only if all circuits have reached the desired temperature. This will be the case with the NT circuit usually by cooling and the MT or possibly the HT circuit usually achieved by heating.

at the inventive circuit, it is now possible, the accumulating Waste heat for temperature control of each of the temperature level higher-lying circulation over the internal Recooling circuit to use.

In this case, a design may be preferred in which the bypass valve 671 a 3-2 way valve (46) and passes only so much heat energy to the free cooler that no additional heat energy must be generated by means of electric heaters for the temperature of the MT and HT circuits.

Once the working temperature of the printing press 1 is achieved and the printing process itself by z. B. Walkarbeit and / or drive motors generated waste heat, it is desirable for energetic reasons that the free cooler gives off as much heat energy as possible to the environment.

The Potential savings here include the environmental conditions and the actual required temperature levels especially the MT refrigeration depended, since the Working temperature of z. B. 20-25 ° C only conditionally completely or partially generated by the free cooler can be.

2 shows a comparable system as in the 1a to 1d , So that duplicate descriptions are avoided. In the figure, except the cold generator 2 additionally a cold producer 4 provided, which are both designed as chillers in the illustrated embodiment.

there Two separate chillers can use the system Optimize further, as the chillers at different Evaporation temperatures can be operated.

There a chiller usually energetically efficient works the higher the evaporation temperature (possible through higher water temperatures) has been shown that there are energetic benefits when taking fluid temperatures from z. B. 10 ° C and 20-25 ° C with separate Chillers produced.

In addition, here is a heat exchanger 684 - By way of example - only provided in a hydraulically separate circuit of the MT temperature control point in order to release heat exclusively or partially via the free cooler. This heat exchanger 684 can be switched off if required by a 2-way valve shown.

As in 2 As can be seen, the chillers are water-cooled systems which transfer their waste heat to the central heat-exchange system 6 z. B. for further use and / or deliver to the free cooler.

3 again shows a comparable system as in the 1a to 1d and 2 , Again, duplicate descriptions are avoided. Also in the 3 is beyond the cold generator 2 additionally a cold producer 4 provided, which is executed in the illustrated embodiment, however, as air-cooled chillers. Preferably, the air-cooled chiller for the average temperature level is not placed in the same room as the printing press. Again, a free cooler is also provided.

About a valve, which in 3 is shown below the air-cooled chiller, the MT and the HT temperature control over a - with open valve further - partial branch 65 the heat exchange circuit 62 with the heat exchange circuit 62 get connected. In this case, both the free cooler and / or depending on the ambient temperature, the air-cooled chiller completely and / or partially connected to it.

4 shows the arrangement with a common heat recovery through a heat consumer system 9 can be supplied with heat. The heat consumption system 9 has a common heat exchanger 91 which is accommodated in the illustrated preferred embodiment in a storage tank which is at least partially filled by a heat storage material, which stores the heat emitted from the heat exchanger. The heat exchanger 91 is therefore at the same time as a heat reservoir 92 executed. Like in the 4 is shown are at the heat reservoir 92 By way of example, at the top and at the bottom, lines are provided, via which heat consumers can be supplied with thermal fluid.

True, is in 4 only through the shortened central feeds 63 or the central processes 64 it can be seen that the illustrated arrangement may preferably have a cooling system, as with respect to the central heat exchange system 6 in 1a to 3 has been described. However, also the illustrated heat consumer system 9 be regarded as a cooling system, since heat is removed from the press via the consumer. The illustrated manner of the pipe system of the heat consumer system 9 and the arrangement of the elements of the leads to the heat consumer system 9 can therefore in the same way in a heat exchange system according to the invention 6 be executed, as well as vice versa.

In the presentation of 4 stand the tempering with the heat consumer system 9 preferably via mutually hydraulically separated temperature control circuits in heat exchanging relationship. The individual hydraulically separated Temperierstellen circuits are preferably via exemplary illustrated circulation valves 653 . 654 the heat exchanger 91 be switchable.

In addition to the temperature control points described so far is here additionally a blown air cooling 7 provided, which also connected to the heat exchanger 91 connected.

As shown, to the heat exchanger 91 Furthermore, further waste heat sources, eg. As the water-cooled chiller, a UV dryer, sheet baffles and the blast or compressed air supply 7 connected, since comparatively high temperature levels are generated for a meaningful use. Other waste heat sources are also conceivable.

The in the heat reservoir 92 absorbed heat is when needed to heat consumers 93 issued.

In the illustrated heat recovery, the different temperature levels in the heat exchanger 91 merged to a mixing temperature which is higher than the lowest temperature level but lower than the highest temperature level.

5 shows a similar arrangement with egg depending on the temperature level separately usable heat recovery.

Here are in the in 5 shown heat recovery individual consumers via their own feed-in circuits with the respective waste heat source, eg. B. thus connected to the individual temperature control. As a result, the individual consumers, advantageously a waste heat source can be assigned, which z. B. has a preferred temperature level. A residual heat flow, which was not taken from the respective fluid flow coming from the temperature control point, is here transferred to the heat exchanger via a common fluid circuit 91 fed, which also serves as a heat reservoir 92 is executed.

To the one from the heat reservoir 92 wegführenden lines may preferably be connected to further heat consumers and / or a cooling device.

At the in 5 As shown embodiment, an example is shown how different temperature levels can be tapped and used separately by means of upstream heat exchangers. Furthermore, after the separate use of the residual heat can be summarized in a waste heat cycle and possibly stored in a downstream heat exchanger and / or buffer tank.
